Find the equation of the ellipse whose axes are along the coordinate axes, vertices are `(pm5,0)` and foci at `(pm4,0)`.

Explanation

Let the equation of the required ellipse be


`(x^2/a^2)+(y^2/b^2) =1 `


The coordinate of its vertices and foci are `(pm a,0) ` and ` (pmae,0)`


But the coordinate of vertices and foci are given as `(pm 5,0)`and `(pm4,0)`
